When trying to build a 32-bit binary on a 64-bit platform, we generally
need to pass "-m32" to gcc, which is not convenient with current makefile.
Note that this option requires gcc >= 3.
In order to ease parameter passing, a new ARCH= makefile option has been
added. If it receives a target architecture, according "-m32"/"-m64" and
"-march=xxxx" will be passed to gcc. Only the generic makefile has been
changed to support this option right now as the need only appeared on Linux.
The spec file now makes use of this option so that rpmbuild can automatically
build with the proper architecture.

* fixed a bug where a TCP connection would be logged twice if the 'logasap'
option was enabled without the 'tcplog' option.
* encode_string() would use hdr_encode_map instead of the map argument.
* the logged request is now encoded with '#XX' for unprintable characters
* new keywords 'capture request header' and 'capture response header' enable
logging of arbitrary HTTP headers in requests and responses
* removed "-DSOLARIS" after replacing the last inet_aton() with inet_pton()
* added the '-V' command line option to verbosely report errors even though
the -q or 'quiet' options are specified. This is useful with '-c'.
* added a Red Hat init script and a .spec from Simon Matter <simon.matter@invoca.ch>
* added 'rspdeny' and 'rspideny' to block certain responses to avoid sensible
information leak from servers.
* more examples added into the configuration
